Air India — Worst airline service

I am sharing my worst ordeal with the airindia TATA.
Flight from Vishakapatnam to Jammu was booked two months well in advance for the travel on 19th and 20th Jan 2023 only to face nightmarish experience.
On reaching Visakhapatnam airport on 19th Jan 2023, My family with two daughters were told that the flight from Delhi to Jammu is not showing in the system. No prior intimation in whatsoever manner was given for the cancellation of flight by email, sms, telecall, whatsapp etc. Nothing did the airindia officials do to confirm booking from Delhi to Jammu nor did they give any assurance. Vizag officials told to reach Delhi and approach Airindia counter.
In Delhi people are so unapologetic, pathetic and irresponsible who said no flights are there and may accommodate in Delhi to Srinagar flight of all the flights.
Star Alliance is an absolute fake and worthless claims that the airlines TATA makes.
My family with two daughters had to wait the entire night in airport for confirmation of next flight as the staff had told to wait near the airindia counter.
My family had to mov to Srinagar in the freezing cold and return to home on own arrangements.
Similar journey flights were booked from Indigo airlines which had cancelled first by giving intimation on email, whatsapp, sms and voice call quoting operational reasons.

Caution from my experience to all passengers seeking airindia TATA.
beware o[censored]nintimated cancellations at last moments and with no support further. The the customer call numbers are not picked up purposefully where I had made numerous calls and the call was dropped without an answer, sometimes picked and dropped and sometimes kept a side,

I urge the highest official to looking into this matter and avoid delivering such painful experiences.
